Sensor in that it is not returning to ZERO PSI, but telling the controller
that there is some PSI. That can also be a bubble in that TV brake
line. It compresses during braking and when the brake pedal is released,
it will expand to keep a bit of PSI in 'that' brake line.
Forgot to mention that there is another issue, IMHO, with MC PSI sensed
That is with MC's that have more than one brake line
As any of the MC PSI sensed only sense
ONE
line
The reason today's MC's have more than one line is a fail safe design
If one line should be damaged, the other line 'might be' or 'should be'
still operational. Albeit only two wheel braking....never the less
braking of lesser degree
If the line that goes south is the one a trailer brake sensor is
on...no trailer brakes...
